Leukocytes
Immune system healthLeukocytes, also known as white blood cells, are crucial for immune system function: the total white blood cell count measures overall immune activity, while differential testing examines specific cell types.

Reference ranges may vary between labs and assays. Always interpret results with your healthcare provider.
Why this matters
Abnormally high or low leukocyte counts can indicate immune system activity or dysfunction. Elevated counts often reflect infections, inflammation, or stress, while low counts may suggest bone marrow issues, certain infections, or immune suppression. Lifestyle factors such as nutrition, sleep, and stress can influence white blood cell levels. Monitoring leukocytes helps track immune health and detect early signs of infection or other immune-related conditions.
